SIMULATIVE CALCULATION FOR SEPARATING THE TRACE OF METHYLCYCLOHEXANE FROM COKING BENZENE BY EXTRACTIVE DISTILLATION |
| |
Abstract: | The conventional and extractive distillation for separating the trace of methyl-cyclohexane from benzene based on the phase equilibirum relations was simulated by the Wang-Hanke BP method and a seperation scheme was pre sented. |

Keywords: | benzene methycyclohexane N N-dimethylormamide(DMF) extractive distillation |
